     .DESCRIPTION
     The `Export-Migration` function exports database objects, schemas, and data types as a Rivet migration. By default, it exports *all* non-system, non-Rivet objects, data types, and schemas. You can filter specific objects by passing their full name to the `Include` parameter. Wildcards are supported. Objects are matched on their schema *and* name.
 
-    Extended properties are *not* exported, except table and column descriptions.
